Hey regiapemid great comparison between the GR07 and the EPH-100. I've been deciding between the two of these for quite sometime and was just wondering how the comfort level and isolation was for you. I listen to mostly bass heavy music like hip hop and trance but still would like a great all arounder.
Thanks! They're both rather comfortable. The EPH-100 has better isolation as it seals more completely - if I insert them in very firmly, there's a very slight "grip" to my ear when I pull them out. The GR07s never generate that "grip" no matter how hard I push them in. Their isolation is not as good as the EPH's, but still decent - no complaints at all from me. I do imagine that this might vary from person to person though, just based off ear canal sizes.
I think ideally you should get both, do your own testing, and return the one you like less. You could even keep them both if they're close enough in performance, as I had hoped to do (I was really hoping I would like the GR07 so I could use it for working out since its better suited to be worn over-the-ear). Everyone has their own tastes after all! I know Amazon is running extended returns until January 31 due to the holiday season and you can pick up a GR07 from there (~180 from what I saw a few days ago). I had to order my EPH-100 directly from Yamaha (~150), but they also have a return policy of course.
